(To be transparent I didn’t quite look at this since I was busy looking for my other issue with the fan)
I got a new Rock5B from Redxa. Plugged the HDMI output, flash a new sdcard with dietpi and won’t see any signal. I find out with the Debian distribution it is working.
When checking at dietpi-config “1 Display Configuration/1 Display Resolution” I got a nice message that it isn’t supported for that board.
I was wondering if there is just no support yet, or maybe if, by the nature of dietpi, I need to install something first to add support for it.
Here, I’m not talking about a desktop environment. Just to be able to have access to the boot/console.
I end up using the serial port (because of some issue with my router not showing up anymore DHCP clients so I didn’t have the IP of the board).
Linux rock5b 5.10.110-rockchip-rk3588 #23.02.2 SMP Fri Feb 17 23:59:20 UTC 2023 aarch64 GNU/Linux
Fresh install without any additional softwares yet.
I can see some log around HDMI
